[[chef-dev]] Re: [[chef-dev]] Modifying the solaris2 Ohai plugin.

["Jason J. W. Williams" < >]

Actually I have put puts in both plugins/platform.rb and 
plugins/solaris2/platform.rb. The latter (stock from opscode except for the 
puts statement) never gets hit. Which also explains why ohai doesn't 
traceback when run on OpenIndiana (it should in its current form because OI 
uses GNU uname which doesn't support the -X option the defacto solaris2 
plugin uses).
